How to use the QM code to achieve the following CMD code effect

[win]

@kevin

I have an interesting problem,   my hard drive has three partitions.

First partition: C: Volume label is SYS
First partition: D: Volume label is SOFT
First partition: E: The volume label is DATA

Sometimes, I want to copy the file to the partition labeled DATA (I don't know the drive letter of the DATA partition)

So I want to get the partition drive (E:)with the volume labeled DATA and store it in the variable s. I don't know how to use QM code. Can you help me? Thanks
